Shelf life assessment of industrial durum wheat bread as a function of packaging system
2017
This study compared the effect of different packaging systems on industrial durum wheat bread shelf-life, with regard to thermoformed packaging (TF) and flow-packaging (FP). Two TFs having different thickness and one FP were compared by assessing physico-chemical and sensorial properties and volatile compounds of sliced bread during 90 days of storage. Texture, aw and bread moisture varied according to a first-order kinetic model, with FP samples ageing faster than TFs. Sensorial features such as consistency, stale odor, and sour odor, increased their intensity during storage. Furans decreased, whereas hexanal increased. The Principal Component Analysis of the whole dataset pointed out that…
Consumer perceptions of product packaging
2006
Purpose – This paper seeks to discuss the need to understand consumer perceptions in order to correctly design product packing and to achieve the desired position in the minds of consumers.Design/methodology/approach – Data collection was divided into two phases. The first, (based on designers' opinions), to determine the key graphic variables in the design of packaging. The second, (based on consumers' opinions), to associate each packaging with a positioning strategy. The seven product‐positioning strategies selected were represented from the consumers' standpoint using multidimensional scaling. Four maps were obtained related to: alternative packaging colours; alternative packaging typog…
Biodegradable Polymers for the Production of Nets for Agricultural Product Packaging
2021
It is well known that the need for more environmentally friendly materials concerns, among other fields, the food packaging industry. This regards also, for instance, nets used for agricultural product (e.g., citrus fruits, potatoes) packaging. These nets are typically manufactured by film blowing technique, with subsequent slicing of the films and cold drawing of the obtained strips, made from traditional, non-biodegradable polymer systems. In this work, two biodegradable polymer systems were characterized from rheological, processability, and mechanical points of view, in order to evaluate their suitability to replace polyethylene-based polymer systems typically used for agricultural prod…
